The RDNS Project

news announcement

The Reverse Domain Name System (RDNS) project was an effort to streamline reverse DNS operations and make it easier for network range users to manipulate related domain objects.

There were two parts to the project:

  • The introduction of a new authorisation mechanism for domain objects
  • A clean up of inconsistencies between data in domain objects as stored in the whois database and reverse delegation information in the DNS



The RIPE NCC undertook a consistency clean-up between 7 January and 1 March 2004. This was necessary to use the whois database as an authoritative source for the generation of zone data.
